In part, Moby-Dick is the story of an eerily compelling madman pursuing an unholy war against a creature as vast and dangerous and unknowable as the sea itself. But more than just a novel of adventure, more than an encyclopaedia of whaling lore and legend, the book can be seen as part of its author's lifelong meditation on America. Written with wonderfully redemptive humour, Moby-Dick is also a profound enquiry into character, faith and the nature of perception.
